Highlights
The performance of embedded systems in
markets such as Single Board Computers
(SBCs), thin clients, consumer electronics,
Point Of Sale (POS) and telecom, is limited by
IDE-based flash disks. A combination of higher
capacity, higher performance devices is needed
to support larger OSs, heavier GUI applications,
a wide variety of installed applications and
local data storage. uDiskOnChip (uDOC)
answers these needs by merging M-Systems’
expertise in three worlds: the USB 2.0 high-
speed interface, the DiskOnChip industry-
standard flash for embedded systems, and the
SuperMAP
uDiskOnChip features:
Protection and Security Features
1
Exceptional read, write, and erase
performance
Built-in proprietary TrueFFS
for full hard-disk emulation, high data
reliability, and maximum flash lifetime
Data integrity with Error Detection
Code/Error Correction Code (EDC/ECC)
based on a combination of BCH and
Hamming algorithms
Support for major embedded OSs, including
Windows XP Embedded and Linux
SuperMAP cryptographic engine to enable
protected partitions
Data protected in hardware with digital
signature: RSA with 64-byte key
cryptographic engine.
